In 2022, international research groups such as Tokyo University of Marine Science and Technology and the University of Western Australia recognized a fish photographed in the deep sea at a depth of 8336,<> meters in the Izu-Ogasawara Trench as "the fish confirmed at the deepest place" by the Guinness World Records, and Japan and overseas researchers were awarded certificates.
In August 2022, an international research group including Tokyo University of Marine Science and Technology and the University of Western Australia successfully photographed the fish at a depth of 8,8336 meters near the bottom of the Izu-Ogasawara Trench, and is considered to be a member of the deep-sea fish family called snailfish, which was recognized by the Guinness World Records as the "deepest fish identified."
On the 4th, at Tokyo University of Marine Science and Technology in Minato-ku, Tokyo, Dr. Hiroshi Kitasato of Tokyo University of Marine Science and Technology, who was involved in the survey, handed a certificate.
According to the group, the deepest depth ever confirmed for live fish was 2017 meters deep in the Mariana Trench confirmed in 8178, and this time it was taken at a depth of 158 meters.
Dr. Kitasato, who received the certificate, said, "It is meaningful that we succeeded in shooting at a very deep place, and I hope that fish will appear in even deeper places in the future."
Professor Alan Jamison of the University of Western Australia, who led the international research group, said: "We are delighted and this discovery highlights how much is still unknown. I think we can make even more discoveries by collaborating and investigating."
